MATHEMATICAL MODELING AND COMPUTATIONAL SIMULATION OF THE ACTIVATED SLUDGE PROCESS WITH OBJECT-ORIENTED PROGRAMMING

Abstract

The project carried out to write this article was made in order to formulate a mathematical model that allows the design of a wastewater treatment plant that includes an activated sludge process, and another mathematical model to simulate the activated sludge process using the DiSimuLAc application. . For this purpose, the most important units in a wastewater treatment plant, their characteristics and design were analyzed for their subsequent computational implementation, taking as units for preliminary treatment: Roughing, De-sanding and Elimination of Fats and oils. Regarding the Activated Sludge process, a detailed analysis of the process, its stages, configurations and the corresponding mathematical description was carried out. The settler that is part of this process was sized according to the characterization of the final effluent from the plant.

DiSimuLAc is the application obtained from the computational implementation of the models that was carried out in Borland® Delphi® for Microsoft® Windows ™ Version 10.0.2288.42451 from Borland® Software Corporation distributed as Turbo Delphi.

This project brings great advances in the field of environmental engineering for both students and teachers since a software was created with the installation CD of the DiSimuLAc application and with its respective user manual, this application simplifies the calculations and allows a development effective design of a wastewater treatment plant with Activated Sludge and the simulation of this process.
